Introduction iTernity is an highly scalable compliant middleware addressing the needs of small, medium-sized and enterprise customers. This is reflected in the solution’s attractive price, practical maintenance-free operation, compatibility with existing servers, SAN, NAS and other backup structures, and transparent data handling. The iTernity API is available over the web service SOAP protocol. The iTernity middleware provides value-added function such as content addressable storage, encryption and compression. Content addressable storage means that the iTernity middleware calculates a fingerprint based on a crypto graphical hash and returns this hash to the application for referencing the object. The iTernity engine is stateless running without any database, this enables a migration and restore by simple file copy. iTernity stores the data in a file system which can either be a local file system in the server or a file system created on NAS (N series), DR550 FSG and SAN storage(DS4500). iTernity also provides load balancing and backup functions. With the load balancing function the iTernity client such as the iTernity MiniArchiver can be configured to write the data to two instances of iTernity. When one instance of iTernity is not available, the other instance is able to access the data. Thereby the data is not duplicated. The backup function allows to create two copies of the data. iTernity can be configured to write all data to two distinct storage systems. If one storage system fails then iTernity can be configured to retrieve the data from the remaining storage system. This document summarizes the tests which have been executed on 7/17 and 7/18/08 in the SLE in Mainz. In the course of these tests iTernity has been tested on IBM System x and the data was selectively stored on IBM N series N3700, IBM DS4500 and IBM DR550 File System Gateway. iTernity plans to submit three applications for the IBM System Storage Proven program, one for each storage system scenario and of cause for the IBM System x.

Test Results Tests with iTernity Software and IBM System x and IBM System Storage has been executed on 17.8.2008 – 18.08.2008 in the System Lab Europe at IBM in Mainz. The test results are backed up by screen-shots in order to demonstrate correctness. All tests have been executed successfully and the expected results were met.

Hardware Details Head Controller with installed iTernity Software: x3550 (7978-A1G) x3850 (8863-3SG) Attached Storage Systems: DS 4500 (1740-90U, Firmware 6.60.08) N series (2863-A20, Data ONTAP Release 7.2.1.1) DR 550 FSG (2229-FSG, FSG Version 1.1.1, DR550 Version 4.5)

Software Details iTernity (Version 3.0.0.34 (Beta)) iTernity Mini Archiver (Version 0.5.0.9 http://iTernityMiniArc.sourceforge.net) iTernity C# Sample (2.7.0.x http://www.iternity.com/de/support/entwickler/sample-code.php) Windows 2003 Server (64-bit)

Installation and configuration After installing the iTernity Software and license codes we opened the SystemInfo in the iAdmin Tool. The screen shows the part of the system information showing the iTernity version (3.0.0.34):

The next step was to change the archive path of the iTernity configuration to an attached storage system:


At the beginning of the test, the storage systems were mapped like: DS 4500 E:\ Fibre Channel attached N series N:\ 9.155.66.130 DR 550 N:\ 9.155.49.178 Like shown in the windows explorer:


Tests with DS4500 Archive Path in SystemInfo:

Write to the DS 4500 system using the iTernity Mini Archiver:


Verify of the written containers with the iAdmin Tool:


History of one of the CSC Containers:

Read back one of the documents:

Data Integrity Test Now we used an editor to change the data of one container to manipulate one container, and try to reload it. The result is that this test failed because iTernity identified the manipulation.



Tests with N series Write to N series:


New directory on N series was created as result of this test.

Migrating data from DS4500 to N series For migration from DS4500 to N series the copy command was used. The picture below shows the copied directory structures on N series.


Now the path had to changed to the N series directory


Retest read of a document which was retrieved from N series – successful


Tests with DR 550 File System Gateway Change of archive path to DR 550:

Change of the Log Path, manually in the C:\iTernity\appSettings.config:

Write to DR 550:


CSC Container on DR550 was created:


Read back from DR550:

Verify on DR550:


History DR550:


Load balancing Test using the iTernity MiniArchiver The iTernity MiniArchiver can be configured to write the data to two instances of iTernity. The data is thereby not duplicated Setup Client, 2 Servers, 1 NAS Storage Client write on both Servers, shutdown one Server, Read with Client

Write process: Server 1: X3850 Server 2: X3550



Shutdown X3550 (address is 9.155.66.60), read file Code_levels_v4.0_1.pdf:

After pressing OK the data is received through the secondary iTernity server.

Backup Configuration with iTernity iTernity allows to configure two target storage devices. In this case the primary path points to N series (N:) and the secondary path points to the file systems on DS4500 (E:)



SystemInfo including backup path:

Write:


Display the files on both storage targets E: - DS4500 N: - N series


Remove file from primary path N series:

Recovery: change of the secondary path to the primary path:


Read one of the recovered files:

Performance Tests (Write, Verify and Read), with 100 documents each with 1 MB: DS4500, No Compression, AES 256 Encryption, 5,20 MB/s:

Read back, 14,88 MB/s:


N series, No Compression, AES 256 Encryption, 3,72 MB/s:

Read back 7,28 MB/s:


DR550, No Compression, AES 256 Encryption, 3,93 MB/s:

Read back, 7,91 MB/s:


Storage Error Injects With this test case different errors have been injected into the storage systems making it more or less possible to retrieve data.

DS4500 Path Failover The DS4500 comprises two controllers representing redundancy. With first test one DS4500 controller has been set offline. Thereby the multi path driver (RDAC) included in the server hosting the iTernity application performs a path failover. Write to DS4500:

Set one DS4500 Controller offline and read.


DS4500 back online, read:

DS4500 Offline This test set both controllers of the DS4500 offline. Thereby the ports for controller A and B on the SAN switch have been set offline. Result is that the data cannot be retrieved.


N series Offline Write on N series:

Set N series offline and attempt to read:


DR550 FSG Offline DR 550 FSG write:

Set DR550 FSG offline and read
